摘要： In accordance with presently disclosed embodiments, a hybrid power conversion system and method are provided. The hybrid power conversion system integrates multiple power sources. An isolated DC/DC converter manages power transfer between the power sources and the DC/DC converter and the power sources are connected such that a full power rating converter is not required. One of the power sources may comprise one or more battery strings, which may be selectively coupled to a DC/AC inverter. In one embodiment, the battery strings may be connected to a lead acid battery. Based on controller instructions, the isolated DC/DC converter replaces the power flow of the lead acid battery with the battery strings. In another embodiment, one or more battery strings may be selectively connected in series with a photovoltaic (PV) panel providing power to a load. When connected to the load, each of the battery strings may provide an incremental step up in power, boosting PV panel power. The number of battery strings that connect to the load at any given time may be based on the power provided by the PV panel and the power requirements of the load.

摘要： The present invention provides a three-port converter with magnetic integration and current ripple cancellation. With magnetic integration technology, the number of magnetic rings is reduced, and the number of driving coupling transformers is also reduced, thereby greatly reducing the size and weight of the whole converter; and with a current ripple cancellation branch, the amount of current ripples flowing through the three ports is very low and close to zero. The three-port converter of the present invention reduces the influence of electromagnetic interference and simultaneously saves the filter cost so that the busbar current and battery current are smoother.

摘要： A power adapter includes a primary side and a secondary side. The primary side rectifies an alternating current voltage. The secondary side is coupled to the primary side, provides a direct current voltage of a specific voltage level to a cable. The second side includes a sensing resistor, and a compensation circuit. The compensation circuit monitors a voltage level across the sensing resistor, and injects a current into the cable based on the voltage level across the sensing resistor.

摘要： A switching control circuit alternately turns on/off, at a switching frequency at which the impedance of a multi-resonant circuit becomes inductive, switching elements with a dead time therebetween. In an operation in the third quadrant of current-voltage characteristics of the switching elements, the switching elements are turned on by supplying a control signal to control terminals of the switching elements, and a dead time is determined so as to satisfy tc≦td
